Inspecting Cutterhead, Gib, and Knives
1. DISCONNECT MACHINE FROM POWER!
2. Carefully clean the cutterhead with a rag, and
with a flashlight inspect the following:
•
Make sure the threaded screw holes do
not contain wood material or sawdust.
• Make sure that the hex socket and the
threads of all cap screws are in good con-
dition. Replace if questionable.
• Make sure any resin or glue buildup
on the cutterhead, gib, and knives is
removed so the knife and gib will sit flat
on the cutterhead.
• Make sure the knives are free of cracks.
If any cracks exist, replace both knives.
Figure 22. Example of removing screws
securing knife to cutterhead.
4.
Use magnets to carefully slide knife out of
cutterhead.
3. Loosen six gib screws securing first knife
(see Figure 22).
Tip: When loosening gib screws, insert hex
wrench firmly into screw head, then twist
wrench with a powerful turn. This method
will break the screw free and help prevent
stripping the head.
